Sys.backup mitigates the challenges of in-house based backup infrastructure such as cost of upgrade and maintenance, flexibility and remote accessibility issues since all backups are done automatically, without user intervention and all data are stored on CARNet’s enterprise storage system.
With aim to improve quality and security of computer systems, primarily servers, CARNet has developed a service that enables users to backup their data remotely in a secure manner. For now, this service is offered to entire GEANT community and provides several advantages over some current backup solutions that are often used. For example, a very common practice for a institution to backup their data on magnetic tape using tape drives, which often required change of tapes on daily bases. Also, it was not unusual to keep those tapes at the same physical locations as the server whose data are stored. This meant that in case of disaster all data from server, as well as the one stored on tapes could be lost. Sys.backup mitigates these issues since all backups are done automatically, without user intervention and all data are stored on CARNet’s enterprise storage system.
Sys.backup is based on bacula, a set of Open Source, enterprise ready, computer programs. The service can be easily setup by installing a custom developed, Debian GNU/Linux based package – bacula-cn. Also, there is customized MS Windows installer for Windows Server OS’s. The content of all files is encrypted using PKI on client side and can only be decrypted on (same) client side.
Backup is done over existing connections to CARNet network and backup jobs are done during late night hours, when the load on the network is at its minimum thus preventing degradation of other services going over the same link.
